I-trigger - kuyinto umshini aphansi digital

Trigger - iyithuluzi elingeyona inkimbinkimbi kuyinto umshini digital. It has ukuzinza ezimbili isimo. Omunye wabo kusethelwe ku- "1", nomunye - "0". isimo Trigger, futhi ukubaluleka ulwazi kanambambili okuyinto kugcinwa therein amasignali okukhipha kunqunywa: Direct futhi nabokhulumile. Uma okukhipha ngqo has a engaba elihambisana bacabanga eyodwa, bese simo sibizwa ngokuthi inhlamvu iyunithi (i-nabokhulumile isignali ezingeni okukhiphayo uhambelana okunengqondo oyigungqu). Uma isakhiwo akuyona, isimo esinjalo zedivayisi ibizwa ngokuthi zero.

Trigger Izinhlobo. ngezigaba

1. Ngokusho indlela ulwazi ukuqoshwa ezishisa kakhulu zikhipha izinhlayiyana trigger indlela futhi undiza. Ngo usuke amadivaysi indlela kwenzeka uma ufaka amasignali idatha ku imibono. Esikhathini kwalokho zokuvumelanisa ukuze ulwazi oluyisisekelo, kukhona ukulawula okokufaka (elilodwa noma ambalwa). Lezi trigger kuthiwa esitshalweni uma ufaka lezi zimpawu control.
2. Ngo Isifaniso kudivayisi zilawulwa ngolwazi lwezibalo labelwe, ashukumisayo olulodwa futhi multistage. Umgomo we operation lapho inhlamvu ukulawula izibalo ukushintsha kudivayisi ngumkhiqizi okokufaka isignali level lokufakwako idatha, kanye nokulawula ashukumisayo - izinguquko nekhono isetshenziswa lokufakwako sedivayisi Semiconductor. amadivaysi Single-esiteji abe nokulawula esiteji, ababili-sigaba - amabili. uhlobo zokuvumelanisa inezinto olulodwa ngekhanda kolwazi ibizwa ngokuthi owodwa umjikelezo, ngokulandelana, nge zokungena ezimbili isigaba - ezimbili-unhlangothi.
3. Ngokusho uhlobo ukugcwaliseka uxhumano okunengqondo isehlane JK-flip-flop, RS-trigger, T-flip-flop, D-flip-flop namadivayisi yezinye izinhlobo.

Amapharamitha oyinhloko zonke izinhlobo trigger kukhona esiphezulu isignali okufakwayo isikhathi, isikhathi ukubambezeleka adingekayo idivayisi usuke futhi sivumele ukusebenza isikhathi.

Zimise izinhlobo inhlamvu okokufaka

• R - lisho kwidivaysi yokufakwayo ehlukile efakwe kule zero isimo.
• S - idivayisi usuke imodi olulodwa.
• K - emnyango wabe jikelele inhlamvu kulungiselelwa zero.
• J - kusho ehlukile kudivayisi usuke Semiconductor esimweni esisodwa.
• T - ukubala kwidivaysi yokufakwayo.
• D - ukushintsha imodi inhlamvu okokufaka, ukuphinda ezingeni okufakwayo.
• C - ukuvumelanisa kwidivaysi yokufakwayo.
• V - control, ukunika amandla okokufaka.

Izinhlobo ezinkulu trigger

1. Okungavumelanisiwe RS-flip-flop. Le divayisi uthi ezimbili ezinzile futhi imibono emibili - R S.
2. T-trigger - uhlobo ethandwa kakhulu kumadivayisi Semiconductor, it has ulwazi olulodwa kuphela (T) input, kodwa-ke kubizwa ngokuthi schetnym.Sinhronny RS-flip-flop ine ukulawula ezengeziwe (C) input.
3. D-flip-flop. Amadivayisi yalolu hlobo futhi libe namanye idatha (D) input bese ukumela ukubambezeleka kwesikhathi.
4. DV-trigger - okungukuthi, empeleni, okufanayo D-flip-flop, kodwa nokuba ezengeziwe (V) ukulawula input.
5. JK-flip-flop. Lolu hlobo idivayisi iyahluka kwenye indlela kulelo value of the akukho-RS-uhlobo idivayisi inhlanganisela kuthiwa nabokhulumile ulwazi olugcinwe.
